what happens if you go into space without a suit

Immediate Effects on the Body
If a human is exposed to space without protection, they wouldn't instantly freeze or explode as seen in movies. However, survival would only last a few seconds.
With no atmospheric pressure, the body would swell like a balloon, but the skin's elasticity would prevent it from bursting. Meanwhile, the gas inside the intestines would expand, causing severe pain. The air rapidly escaping from the lungs would also damage lung tissue.
Effects on Bodily Fluids and Circulation
In a vacuum, bodily fluids begin to evaporate. The moisture on the tongue and eyes would start boiling, while blood would form bubbles, disrupting circulation.
Loss of Consciousness and Death
Without oxygen, consciousness lasts for about 15 seconds before brain function stops. Holding your breath could cause lung rupture, so staying still would be a slightly better option.
Even in the best-case scenario, death occurs within one to two minutes. Since space lacks bacteria for decomposition, the body would dry out and remain intact for millions of years, floating endlessly.
Final Thoughts
The conclusion is clear. Space is not a place for unprotected humans.
